Abstract

　複数の端末装置においてデータ受信タイミングを同期させる技術を提供する。通信装置は、処理遅延時間を取得する処理情報取得手段と、各伝送遅延時間をそれぞれ取得する伝送情報取得手段と、配下ノード以後の到達時間を各配下ノードからそれぞれ収集する収集手段と、処理遅延時間、伝送遅延時間及び各配下ノード以後の到達時間に基づいて、配信データが自ノードで受信されてから複数の端末装置に到達するまでの時間を、自ノード以後の到達時間として、配信データが経由される配下ノード毎にそれぞれ算出する算出手段と、当該配下ノード毎の自ノード以後の到達時間に基づいて、上記複数の配下ノードの少なくとも１つへの上記配信データの送信タイミングを制御する送信制御手段と、を備える。
